1. An antimicrobial cap that is configured to disinfect a medical connector or catheter when the antimicrobial cap is inserted into a channel containing a liquid in the medical connector or catheter, the antimicrobial cap comprising:
a threaded portion;
a male luer base extending along a longitudinal axis from a proximal portion of the antimicrobial cap, the male luer base having a cross-sectional diameter measured perpendicular to the longitudinal axis; and
an elongate portion extending along the longitudinal axis from a distal end of the male luer base, the elongate portion extending distally beyond the threaded portion from the distal end of the male luer base, the elongate portion having a solid cross-section and a water-soluble dry antimicrobial agent on at least an outside surface of the elongate portion, the cross-sectional diameter of the male luer base at the distal end is greater than a cross-sectional width of any portion of the elongate portion;
wherein the antimicrobial cap is configured so that, as the elongate portion is inserted into the channel in the medical connector or catheter, at least some of the water-soluble dry antimicrobial agent is configured to transfer from the elongate portion of the antimicrobial cap into the liquid in the medical connector or catheter, and the male luer base is configured to create a fluid tight seal with an inner wall of the medical connector or catheter, and at least some of the liquid in the medical connector or catheter is displaced to flow out of a proximal opening of the medical connector or catheter and onto an exterior surface of the medical connector or catheter; and
wherein the threaded portion is configured to attach to an outside surface of the medical connector or catheter.
